Nutrient provision capacity of alternative livestock farming systems per area of arable farmland required

Abstract Although climate impacts of ruminant agriculture are a major concern worldwide, using policy instruments to force grazing farms out of the livestock industry may diminish opportunities to produce nutritious food without exacerbating the food-feed competition for fertile and accessible land...
